Abstract
The utility model discloses an electric heater with high heat radiating efficiency, belonging to heating equipment. An electric heating tube inside the lower part of an electric heater shell is supported on a rear panel inside the electric heater shell through a support piece fixed on a ceramic column and a ceramic insulation rack; a temperature sensor is clamped and pressed on the rear panel in the electric heater shell through an elastic clamping piece and is connected with a thermal protection device; a power switch is connected with electric heating tube fuses; and a shutter type hot gas radiating plate is fixed on a front panel of the electric heater shell. The electric heating tube of the electric heater adopts the full-isolation mounting mode and adopts a super-long fin type electric heating tube, so that the power density in work is very low, the radiating area is large, and the service life can reach 50 years theoretically; by adopting the liquid expansion type capillary thermal protection device, high temperature control precision, large detection area, and accurate room temperature control are realized,, so that indoor environment is warm and comfortable, and energy and cost are saved; and compared with the traditional heating system, a user can take the self-heating mode, and the electric heater is simple for installation and low in cost.
Description
Technical field
The utility model belongs to the heating equipment scope, particularly a kind of electric heater of high cooling efficiency.
Background technology
Existing commercially available electric heater has electric heating installation using oil as medium, infrared warmer, Electrothermal fan, and also having a kind of is the Infrared Heating thin type electric heater that newly comes out; But wall hanging, can be placed on arbitrarily Anywhere indoor, but the thermal efficiency is low; Radiating surface is little; The fan noise in addition that has causes environmental pollution, takes shortcomings such as electricity; The electrical heating heater great majority of commercially available in addition electric heater are independent electric heating tubes, and the area of dissipation of electric heating tube own is very little, and radiating efficiency is lower, and electric heater for heating power is big, and it is short to take electricity and life-span.Existing residential central air conditioning does not reach satisfied heating effect, and fan noise is very big, and contaminated environment is taken electric problem and is difficult to solve; The light water warmer receives people's favor, but thermal efficiency ratio is lower.
The utility model content
The purpose of the utility model is low to the electric heater thermal efficiency in the prior art, and radiating surface is little, the fan noise in addition that has; Cause environmental pollution, take shortcomings such as electricity, and the area of dissipation of electric heating tube own is very little; Radiating efficiency is lower, and electric heater for heating power is big, and expense electricity and life-span, short deficiency provided a kind of electric heater of high cooling efficiency; It is characterized in that the electric heating tube of bottom is supported in the electric heater shell on the rear board by being fixed on supporting pieces and ceramic insulation frame on the ceramics pole in the electric heater shell, temperature sensor is pressed in rear board top in the electric heater shell by the elastic card card; And be connected with thermal protector; Joint of thermal protector and electric heating tube is connected with power switch, connects protective tube between another joint of power switch and electric heating tube, and circulation of air mouth in the back also distributes on the plate; The abatvent formula hot gas eminator on the front panel top of electric heater shell.
Said electric heating tube is finned electrothermal tube, i.e. welding screw type radiating fin on the straight-tube portion outer surface of stainless steel electrothermal tube outer surface.
The material of said radiating fin is stainless steel band, aluminium strip or copper strips.
The total heat conduction area of said finned electrothermal tube is A; Electrothermal tube light pipe area with fin is A0, then the finned electrothermal tube used on the engineering in heating than A/A0 of wingization its between 5---12, and at air-conditioning; Air cooling industry, its wingization than A/A0 between 15-22.
Said temperature sensor and thermal protector connect to form liquid expanding capillary heat protector, and structure is identical with tubular type temperature controller in the refrigerator.
Said electric heater shell is square or rectangle.
The utility model beneficial effect be that the utility model electric heater electric heating tube all adopts the mounting means of isolating fully; Be that electric heating tube passes through high insulation high-intensity " 95 " pottery and is connected with casing with nylon PA; Accomplished that really electricity separates with body, heat is separated with body, reached high-grade safety guarantee; With overlength helical fin calandria, the life-span is long, the plate temperature is low, uses more safe and reliablely, is suitable for the characteristics that engineering is used long-time non-stop run.
Adopt the Natural Heat Convection form, thoroughly changed common electrical warmer near-thermal cold sensation far away, make indoor each position temperature even; No intermediate medium, electricity directly add hot-air, heat up rapidly, and the thermal efficiency is near 100%; The sensation of hot-water heating does not but have the worry of run, drip, leak; Independently heating of user does not receive the constraint of extraneous time, temperature.
Adopt high-precision temperature control system, can control room temperature accurately, can make indoor snugness, again can energy savings and expense; System compares with traditional heating, and installation is simple, expense is low.

The specific embodiment
The utility model provides a kind of electric heater of high cooling efficiency.Explain below in conjunction with accompanying drawing.
In Fig. 1, electric heater structural representation shown in Figure 2; Bottom in electric heater shell 2; Electric heating tube is supported on the electric heater shell 2 interior rear boards (as shown in Figure 3) with ceramic insulation frame 4 by the supporting pieces 9 that is fixed on the ceramics pole 14, and temperature sensor 11 is pressed in rear board tops in the electric heater shell 2 by elastic card 10 cards, and is connected with thermal protector 13; Temperature sensor and thermal protector connect to form liquid expanding capillary heat protector, and structure is identical with tubular type temperature controller in the refrigerator.Thermal protector 13 is connected with power switch 1 with a stature of electric heating tube joint 6 respectively, connects protective tube 3 between another joint of power switch 1 and electric heating tube joint 6, and circulation of air mouth 12 in the back also distributes on the plate; Front panel 18 top abatvent formula hot gas eminator 19 at electric heater shell 2.
Said electric heating tube is finned electrothermal tube, i.e. welding screw type radiating fin 8 on the straight-tube portion outer surface of stainless steel electrothermal tube 7.The material of radiating fin 8 is stainless steel band, aluminium strip or copper strips.
